Abstract
This is a novel xerographic marking system having a novel toner waste dispensing assembly. The assembly comprises a hermetically sealed outer box that houses a disposable waste toner container. The container is a biodegradable carton or bag that can be removed from the outer box when filled with waste toner. A feature of this invention is that the dispensing assembly can easily be retrofitted into existing marking systems. Also because the containers are inexpensive and biodegradable, the expensive prior art non-degradable waste containers and their adverse effect on the landfills can be avoided.
